Federal agents and Los Angeles police officers swept through MacArthur Park, South Los Angeles, and Calabasas on May 6, 2026, in a massive coordinated operation that resulted in 18 arrests and the seizure of more than $10 million in fentanyl. Twenty-five defendants are named in a federal criminal complaint alleging large-scale distribution of fentanyl and methamphetamine on behalf of the 18th Street Gang.

Federal narcotics cases of this size carry mandatory minimum sentences and life-changing consequences for everyone named in the complaint. The defense work in a federal drug investigation must begin immediately — long before the first court appearance.

What Happened

The U.S. Attorney’s Office for the Central District of California announced charges on May 6, 2026, against 25 defendants accused of distributing fentanyl and methamphetamine in and around MacArthur Park, just west of downtown Los Angeles. The operation, dubbed “Operation Free MacArthur Park,” was led by the Drug Enforcement Administration and involved more than 300 federal and local law enforcement personnel, including approximately 100 Los Angeles Police Department officers.

According to the federal complaint, investigators tracked 27 separate drug deals for fentanyl and methamphetamine in the MacArthur Park area over a nearly six-week investigation that began in March 2026. Authorities allege the drugs originated with the Sinaloa Cartel and were distributed through a street-level network operating in what officials described as an “open-air drug market” along the Alvarado Corridor.

Prosecutors identified Mallaly Moreno-Lopez, 31, and her boyfriend Jackson Tarfur, 28, both of the Westmont area of South Los Angeles, as among the main suppliers of fentanyl and methamphetamine in the Alvarado Corridor and MacArthur Park area, allegedly acting on behalf of the 18th Street Gang. Authorities allege the couple hand-delivered narcotics to the area for stashing in storefronts and later distribution to street-level dealers. During the raid on their Westmont residence, agents allege the couple attempted to flush fentanyl evidence down the toilet. Two additional named defendants — Yolanda Iriarte-Avila, 40, of Calabasas, and Jesus Morales-Landel, 33 — were identified as a methamphetamine supplier and a street-level dealer, respectively. Approximately 18 kilograms (about 40 pounds) of fentanyl was seized at the Calabasas residence alone.

Of the 25 defendants charged, 18 were arrested during the May 6 operation, with seven others remaining at large as fugitives. Federal officials said the operation included nine search warrants — six in MacArthur Park and three in South LA and Calabasas. Cases against the arrested defendants will proceed in the U.S. District Court for the Central District of California.

First Assistant United States Attorney Bill Essayli said the operation is part of an ongoing federal effort to dismantle the open-air drug market that has operated near MacArthur Park for years. The investigation remains active, and additional arrests or superseding charges could follow as fugitives are located. All defendants are presumed innocent unless and until proven guilty in court.

Charges Involved

Federal Possession With Intent to Distribute — 21 U.S.C. § 841

The core federal narcotics charge under 21 U.S.C. § 841(a)(1) applies to anyone who knowingly possesses a controlled substance with the intent to distribute it. Penalties depend on the type and quantity of drug involved:

  • 40 grams or more of fentanyl — mandatory minimum of 5 years, maximum of 40 years
  • 400 grams or more of fentanyl — mandatory minimum of 10 years, maximum of life in prison
  • 5 grams or more of methamphetamine (pure) — mandatory minimum of 5 years
  • 50 grams or more of methamphetamine (pure) — mandatory minimum of 10 years

If a death or serious bodily injury results from the distributed drug, the mandatory minimum jumps to 20 years and can extend to life. Given the alleged 40-pound (~18 kg) fentanyl seizure in Calabasas, top defendants face the highest tier of penalties.

Federal Drug Conspiracy — 21 U.S.C. § 846

Federal drug conspiracy is one of the most powerful tools available to prosecutors. Under 21 U.S.C. § 846, a conspiracy charge carries the same penalties as the underlying distribution offense — but it allows the government to introduce statements and conduct of co-conspirators against each defendant, dramatically broadening the evidentiary picture at trial. Conspirators can be held responsible for drug quantities they never personally touched, as long as the conduct was reasonably foreseeable within the scope of the agreement.

Gang Allegations and Sentencing Enhancements

While the current charges are federal narcotics offenses, allegations of gang affiliation — in this case, ties to the 18th Street Gang — can lead to additional charging decisions. Federal prosecutors may pursue RICO charges (18 U.S.C. § 1962) or Violent Crimes in Aid of Racketeering (VICAR) charges (18 U.S.C. § 1959) in superseding indictments if the evidence supports them. Even without separate charges, gang affiliation can affect U.S. Sentencing Guidelines calculations and pretrial detention decisions.

Firearms Enhancements — 18 U.S.C. § 924(c)

If firearms are recovered in connection with a federal drug case, prosecutors can charge possession of a firearm in furtherance of a drug trafficking crime under 18 U.S.C. § 924(c). This adds a mandatory consecutive 5 years to any underlying sentence — and significantly more if the firearm is a machine gun, short-barreled rifle, or used in a violent act. These enhancements stack on top of the underlying drug sentence and cannot run concurrently.

Forfeiture and Civil Asset Seizure

Federal narcotics prosecutions typically include asset forfeiture allegations — meaning the government can seek to seize cash, vehicles, residences, and any other property allegedly used in or derived from the drug operation. Defending against forfeiture often runs on a parallel track to the criminal case and requires its own legal strategy.

Federal vs. State Court

This case is being prosecuted in federal court, where sentencing is governed by the U.S. Sentencing Guidelines and mandatory minimums apply to most drug counts. Pretrial release is harder to obtain in federal court — particularly in fentanyl cases involving alleged cartel and gang ties — and the federal system does not offer state-court options like California’s Health and Safety Code § 11352 alternatives. Whether a defendant has any path back to state court is one of the first strategic questions defense counsel must address.

What Defendants and Their Families Should Know

If you or a loved one has been arrested or contacted in connection with a federal narcotics investigation, the most important protection is your right to remain silent. DEA and FBI agents are highly trained interrogators, and statements made before counsel is present can be used to support conspiracy, distribution, and firearms charges that may not have been formally filed yet. Politely decline to answer questions and ask for an attorney before any further contact — this includes proffer interviews, “off the record” conversations, and any meeting where the agent suggests cooperation.

Federal cases are fundamentally different from state cases. The U.S. Attorney’s Office operates under the U.S. Sentencing Guidelines, mandatory minimums apply to most fentanyl and methamphetamine charges, and pretrial release is far harder to obtain — especially in cases involving alleged cartel or gang ties where detention is presumed. The first 48 to 72 hours after arrest are critical: an experienced criminal defense attorney can appear at the initial appearance and detention hearing, challenge the government’s evidence for pretrial detention, and begin reviewing the affidavit and complaint for weaknesses long before trial.

Families should also understand what to expect at the initial appearance and arraignment. The defendant will be advised of the charges, asked about counsel, and the court will address detention. Loved ones should avoid discussing case details on jail phone calls or in visits, as those communications are recorded and routinely used as evidence. Anything sent in writing or said in a visiting room can become an exhibit in a federal case where the government already has wiretaps, surveillance video, and informant testimony.

Early intervention by counsel matters because federal investigations almost always continue after the first wave of arrests. Cooperators are identified, superseding indictments are filed, and the evidentiary picture can shift quickly. An experienced attorney can engage with prosecutors early, preserve favorable evidence, identify constitutional issues with searches and wiretaps, evaluate whether a defendant has any cooperation leverage, and protect options before they narrow. Every defendant in this case is presumed innocent unless and until proven guilty in court — and that presumption is the foundation of every federal criminal defense.
